BTW, 2.6.18+ kernels have still CONFIG_UBC_DEBUG_KMEM=y which affects this microbenchmark pretty badly.
So if you have a chance, please recheck without it.

on 2.6.18-028stab031.1 kernel and 16 CPUs Intel machine we get the following:

kernel                             030.1   RHEL5  030.1 (*)
FINAL SCORE                        450.4   471.7  481.7

(*) - it is 030.1 kernel with CONFIG_UBC_DEBUG_KMEM=n
